Building J2EE Web Applications

Course Overview

Java 2, Enterprise Edition (J2EE) is a powerful platform for building web applications. The J2EE platform offers all the advantages of developing in Java plus a comprehensive suite of server-side technologies. This course tells you what you need to know to design and build your own web applications. You'll learn the details of the key J2EE technologies and how to leverage the strengths of each, with special focus on Servlets and JSPs. At the same time, you'll be learning about the big picture of J2EE and how to design web applications that are robust, efficient, secure, and maintainable. If you want to deliver an application on the web, you'll find this course essential.

The course begins with a discussion of web application architecture. A major part of the course is spent on Servlets and JavaServer Pages (JSP). It then covers interacting databases using JDBC, Java's database access technology. The course includes an introduction to Enterprise JavaBean technology and addresses the newest J2EE web component - Web Services. The course concludes with an examination of J2EE and web application security providing students with an understanding of the importance of defensive coding practices. Throughout the course, students will create code for an online store. Students will learn not only specific topics and APIs but also how to fit the pieces together into a complete application.

Audience

The course is designed for Java developers who want to create web applications and anyone who wants to understand the architecture of a Java web application.

Prerequisites
